Šifner, František, 2020, Scathophaga karmazini nov. sp., a new species from Austria, with a key to Scathophaga species from Central Europe (Diptera, Scathophagidae), Linzer biologische Beiträge 52 (1), pp. 731-757 : 737

Scathophaga pictipennis (OLDENBERG, 1923) ( Figs 45–48 )

M a t e r i a l e x a m i n e d: CZECH REPUBLIC: Šumava Mts. , Malá niva (7048), 1♂, 19.v.1999 ; Krkonoše Mts. (5259), louka, meadow, 21.vi.1966, 1♀, Šifner leg. ( FSPC) .

D i a g n o s i s. Male. The abdominal sternite 5 with two distinct lobes which are apically pointed and bristled, sternite 4 quadrate, sternite 3 oval and sternite 2 rectangular

( Fig. 45 ), surstyli slightly arched, cerci wide and narrowed caudally, both densely haired

( Fig. 46 ), pregonite enlarged apically, with two setae ( Fig. 47 ).

Female. The abdominal sternite 7 wide caudally, sternite 6 to 4 oval ( Fig. 48 ).

C o m m e n t s. In the male of this species sternite 5 with lobes; these lobes are developed among Central European species only in S. litorea and S. intermedia ; among the northern species they occur in S. apicalis (CURTIS, 1835) , S. calida (HALIDAY, 1832) , S. islandica ( BECKER, 1894) , and newly described S. simaceki ŠIFNER, 2018 from Svalbard ( Norway) ( ŠIFNER 2018) and S. yakutica OZEROV, 2017 from Russia (Yakutia) ( OZEROV 2017)). OZEROV (2017) in this connection states: “ S. pictipennis together with S. yakutica form a separate group of species, its taxonomic position still remains unclear”. I confirm in this connectin only that in all other species of Scathophaga in its present concept the sternites 5 are of a different shape or not developed.

D i s t r i b u t i o n. Only known in Austria, Czech Republic, Germany and Slovakia ( ŠIFNER 2018).
